X Mangave plant named ‘Fiercely Fabulous’

ABSTRACT

A new and unique X Mangave plant named ‘Fiercely Fabulous’ characterized by compact habit of lanceolate foliage with medium grayish-green color and grayed-purplish spots and burgundy air-brushing with strong ultraviolet light exposure. The new plant has numerous chartreuse flowers with burgundy blushing on tall, stiff, highly-branched scapes. The new plant is suitable as a potted houseplant plant, as a container plant for the patio or garden and for the garden or planted in the landscape, and the flowers are loaded with nectar for attracting hummingbirds.

Botanical classification: Manfreda x Agave hybrid.

Variety denomination: ‘Fiercely Fabulous’.

STATEMENT REGARDING PRIOR DISCLOSURES UNDER 37 CFR 1.77(b)(6)

The first non-enabling public disclosure of X Mangave ‘Fiercely Fabulous’ was on Mar. 2, 2020 as a brief description and photo on two websites operated by Walters Gardens, Inc. Information for this website and plants for this sale were obtained from the inventor. No plants of X Mangave ‘Fiercely Fabulous’ have been sold, in this country or anywhere in the world, nor has any disclosure of the new plant been made, more than one year prior the filing date of this application, and such disclosure within one year was either derived directly or indirectly from the inventor.

BACKGROUND OF THE INVENTION

The present invention relates to the new and distinct X Mangave plant, X Mangave ‘Fiercely Fabulous’ hybridized on Nov. 20, 2015 by the inventor at a wholesale perennial nursery in Zeeland, Mich., USA as a cross between an unreleased proprietary hybrid X Mangave known by the breeder code 12-3-31 as the female or seed parent and an unreleased proprietary hybrid X Mangave known by the breeder code 12-11-2 as the male or pollen parent. Through trials at the same nursery the plant was referred to by the code 16-22-12. The new plant has been successfully asexually propagated initially in 2018 by shoot tip tissue culture at the same nursery in Zeeland, Mich. This asexual propagation system has been found to produce stable and identical plants that maintain all the unique characteristics of the original plant in successive generations.

BRIEF SUMMARY OF THE INVENTION

X Mangave ‘Fiercely Fabulous’ differs from its parents as well as all other Manfreda, Agave and X Mangave known to the applicant. The most similar known X Mangave cultivar known to the inventor are: ‘Silver Fox’ U.S. Plant Pat. No. 29,642, ‘Mayan Queen’ U.S. Plant Pat. No. 31,312, ‘Catch a Wave’ U.S. Plant Pat. No. 29,723, ‘Moonglow’ U.S. Plant Pat. No. 29,195, ‘Aztec King’ U.S. Plant Pat. No. 32,151, ‘Desert Dragon’ U.S. Plant Pat. No. 31,311, ‘Inkblot’ U.S. Plant Pat. No. 29,431, and ‘Freckles and Speckles U.S. Pat. No. 30,904.

‘Silver Fox’ has a more compact habit and lacks the grey-purple spotting. ‘Mayan Queen’ lacks the grey-purple spotting. ‘Catch a Wave’ has leaves that are a more silvery-blue coloration and the leaves are more folded. ‘Moonglow’ has narrower leaves that lack the large teeth, and the habit is flatter. ‘Aztec King’ has broader leaves on a larger habit and lacks the large marginal teeth. ‘Desert Dragon’ has narrower leaves with a more undulating margin and lacks the large marginal teeth. ‘Inkblot’ has flatter growth habit, the leaves arch more, are longer, thinner and narrower, with less burgundy airbrushing, and the marginal teeth are smaller. ‘Freckles and Speckles’ has narrower, shorter foliage with smaller spotting, lacks the large marginal teeth, and has a smaller, less arching habit.

The female parent has bright yellow flowers on heavier branched scapes and the foliage lacks the greyed-purple spotting of the new plant. The male parent has wider leaves with greyed-purple spotting and the habit of the foliage is more upright.

The new plant, ‘Fiercely Fabulous’, is unique from all of these variegated Agave, X Mangave and Manfreda known to the inventor by the following combined traits:

-   -   1. Compact mounded habit with 30 to 40 leaves at flowering;     -   2. About with 30 to 40 lanceolate leaves at flowering;     -   3. Foliage with large flexible marginal teeth and semi-flexible         sharp apical mucro;     -   4. Leaves develop grayed-purplish spots and burgundy air         brushing with strong ultraviolet light exposure;     -   5. Moderate to rapid growth rate;     -   6. Numerous flowers of chartreuse with burgundy blushing on         stiff, tall, highly-branched scapes.

BRIEF DESCRIPTION OF THE DRAWINGS

The photograph of the new plant demonstrates the overall appearance of the new plant including the unique traits as a three-year-old plant grown in a full-sun trial garden with supplemental water and fertilizer as needed. The colors are as accurate as reasonably possible with color reproductions. Ambient light spectrum, temperature, source and direction may cause the appearance of minor variation in color.
